METAL raoxaen.

Original application filed April 16, 1813, Serial No. 781,586. Divided and this 1918. Serial No. 87,842.

To all whom it may concern:

Be it known that I, JOHN W. DARLEY, J r., a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Metal Packages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improvements in metal packages, especially in those metal packages such as barrels, kegs, or SlIIlllar containers, wherein the parts are constructed of standard units which may be conveniently transported in the unassembled condition, and speedily and economic: lly assembled when needed as a container.

The object of my invention is to provide a new and improved means for securin the heads of the containing vessel to the body portion in such a manner as to provide great rom the inside "of the container outward y, and yet permitting of the ready removal of said heads when the contents of the container are to be removed.

This application is a division from my application for U. S. Letters Patent for improvements in metal packages, Serial No.

,761586, filed April 16, 1913.

My invention will he understood by reference to the accompanying drawings in which Figure 1 is a perspective view showing the package in the completed condition;

Fig. 2 shows a central vertical section through one half of the package shown in Fi 1' Figitl is a perspective view of one of the staves which form a part of the body of the package;

Fig. 4: is a detail showing the parts on a larger scale, along the lines 4-4: of Figs. 1 and 2" Fig: 5 is 9. pers ective view of one of the retaining rings or the head, which also forms part of the chine of the containers; and

Fig. 6 is a perspective view of one of the chine hoops detached from the container.

Referring to the drawings, 1 shows one of the staves, each of which is formed out of Specification of Letters Patent.

application filed March 29,

a single plate of metal, such-as rolled steel, made in blanks suitably formed, which blanks are provided with flanges 2 at each side, which are bent to form channels 3 inside of the inturned flanges 4. These staves are also preferably provided with sockets 5 stamped therein, with holes 6 near each end, and with curved grooves 7 at each end, for purposes hereinfter explained The staves are connected together by the locking strips 9. These strips 9 are formed of rectangular blanks of metal similar to that used for the staves, and are used in assembling the barrels, as set forth in the parent application above referred to. The exterior of the barrel is strengthened with two or more hoops 12, which are pro ided with tongues 13 formed in the hoops, and orthese heads rests upon the ends 8 of the flanges 2, which flanges thus form a rigid support for the heads against stresses acting inwardly. The heads are held against stresses actin outwardl by the retaining rings 15 which are provi ed with a series of lugs 16 pressed outwardly from the periphcry of said ring 16, as shown in Figs. 4 and 5. These lugs 16 project into the holes 6 in the ends of the staves 1. It is obvious that the lugs 16 and holes 6 should register, but they may be placed any desired distance apart, that is, there may be one lug and one corresponding hole for each stave, or they may be provided for each alternate stave, as indicated in Fig. 5. Similarly the staves 1 may be each provided with the indentations 5, and the number of tongues 13 of the hoops 12 may be such that there will be a tongue for each depression 5, or each alternate stave may be provided with depressions 5 and the number of tongues 13 be made to correspond. In practice, it will be sufiicient to have one tongue 13 and a corresponding indentation for each alternate stave, and a hole 6 and a corresponding lug 16 for each alternate stave, or each stave may be provided with indentations 5 and holes 6, and the tongues 13 and projections 6 used at each alternate stave.

The chine of the barrel is completed by the chine hoop 18, which is formed with a curved groove 19 in the top thereof, terminating in the outer ring 20 adapted to fit outside of the ends of the stave's 1, The curved groove 19 also terminates in the inner ring 21, leaving a throat 22 between said rings 20 and 21, as shown in Figs. 2 and 4:. The ends of this chine hoop 18 abut, and are connected together by the butt straps 24 riveted thereto, as shown in Figs. 1 and 6, or the butt straps may be omitted, the hoop being held in place by engagement with the ends of the staves, or, if desired, the chine hoop may be made in the form. of a continuous ban The parts are assembled as follows The staves havin been bentto the desired bilge, or desire vertical curvature, and with'the desired circumferential curvature, are assembled in a former (not shown) and then the locking strips 9 are forced down over the flanges 4 of each pair of adjoining staves, thus firmly locking the adjacent staves together.

The locking strips are preferably made somewhat shorter than the distance between the shoulders 8 at the opposite end of the stave flanges to avoid the necessity of accurately fitting the same, and the shoulders 8 of the staves 1 furnish a sufliciently rigid su port for the head 14.

he hoops 12 are made to fit snugly over the body at the desired distance on each side of the crown of the bilge, and they are forced down to this position, and then the tongues 13 are bentinto the notches 5, thus firmly locking the heads 12 against movement toward the heads of the container. If desired, thehoops 12 may be arranged ,sufliciently close to the crown of the bilge for the container toroll on the same,\or a separate band may be applied to the center of the container for this purpose, but in ordinary practice the two hoops, such as shown in Figs. 1 and 2, are sufficient. After the hoops 12 are laced in.- position, one

head 14 is forced 1n. The retaining ring.

15 for said head is then forced into place and the lugs 16 of said ring sprung into corresponding holes 6 in the staves 1. The

resiliency of the metal in the ring 15' will permit of this being down and yet insure a snug fit of the ring against the ends'of the stave and against the outer parts of the head when the parts are assembled, as shown in Figs. 1 and 2.

It will be seen that these retaining rings 15 not only lock the heads 14 against stresses acting outwardly, but also hold the heads 14 firmly in engagement with theends of the flanges 8.

.by rough handling,

When the head 14 and ring'15l have been placed, as just described, the chine hoop,

such as shownin vFigfifi, is then applied.

It is forced down over the hook-shaped ends formed by the grooves 7 on the staves 1.

18 provides a rounded surface which will permit of the handling of the barrel without liability of injury to the hands of the laborers. g

In ordinar usage,..the container would be set up with one. head only in place, and the other head with its corresponding retaining ring and chine hoop would, of course,

as shown in Fig. 4, and the chine hoop,

and-the curved portionsurrounding the groove 19 of the chine hoop be separate therefrom. The package is then filled with the'material to-be transported, the head is put into place, the retaining ringisapplied, as already described, and then the chine hoop is sprung on, thus com letin the package. Afterthe container has een lled and both heads applied when it is desired to open the same, 1t wi first be necessary to force off one of the chine hoops which canbe readily done with a calking tool and a hammer, and then the corresponding retaining ring 15 is removed. This can be done by simply springing the lugs 16 inwardly until'they are disengaged from the corres onding hole 6, as by the insertion of a chisel between the ring 15 and theend of the stave 1. Then the entire ring may be pulled out, leavin the head 14 loose.

By forming the chine oop as shown, the curved portion surrounding the curve 19 .afiords great strength against strains commg on the chine at an angle and tending to deform the same when the container is tipped up on end. I

It will be noted that I provide a strong, cheap, simple and eflicient container which ma be readily assembled, and may be safely an conveniently moved when filled.

The container also provides great strength in a light package.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is 1. A barrel formed with staves having shoulders for the head and perforated and hooked ends, a head fitting on said shoulders, a locking ring having studs adapted to be sprung into said perforations, and a chine ring hook-shaped in cross section and sprung over and engaging said hooked ends, substantially as described.

2. In a barrel the combination with metal staves provided with shoulders to receive the head, with hooked ends, and with perforations therein near the ends thereof, of a head having an annular flat portion to engage said shoulders, a metal locking ring provided with studs adapted to engage in said perforations and to hold said head in place, and a chine ring hook-shaped in cross sections, and sprung over and engaging the ends of said staves, substantially as described.

3. In a barrel the combination with metal staves provided with shoulders to receive the head, with hooked ends, and with perforations therein near the ends thereof, of a head having an annular flat portion to engage said shoulders, a metal locking ring provided with studs stamped out of the metal of said ring and adapted to engage in said perforations and to hold said head in place, and a chine ring hook-shaped in cross section. and sprung over and engaging the ends of said staves, substantially as described.

4. In a barrel the combination with metal staves having hooked ends and provided with shoulders to receive the head, of a head adapted to engage over said shoulders, a locking ring mounted over said head, and a chine ring hook-shaped in cross section, sprung over and engaging the ends of said stares and bearing against said locking ring, substantially as described.

5. In a barrel the combination with a plurality of staves having hook-shaped ends, said staves being provided with shoulders to support the head of the barrel, of a head engaging said shoulders, a locking ring mounted exterior to said head, and a chine ring hook-shaped in cross section, sprung over the hook-shaped ends of the staves and.

engaging said locking ring and serving not only to assist in holding said head in place but also to stiffen the chine of the barrel, substantially as described.

In testimony whereof, I afiix my signature.
